' L. are made much shorter and more compact than is usual, their mounting and connection with the belt shifting mechanism are simplified, and the pressures counterbalanced so that there is a resulting decrease of strain upon the machine and consequently lighter construction may be used.

Our invention will be understood by reference to the drawings, in which it is shown embodied in the preferred manner.

Figure l is a front elevation of the mechanism referred to and Fig.2 an end elevation, the shafts, etc., in each case being in section.

Only so much of the machine is shown as is necessary to illustrate the arrangement to be described.

A is a portion of the frame. A is the beater and B, B the feed rolls, all of which together with the ticing roll C are operated in the usual manner.

A A are supports adjustably mounted on top of the frame A and connected by the girt D. In these supports the feed rolls B, B and ticing roll C are mounted, this construction being such that these parts and other parts supported therefrom may be adjusted bodily toward and from the beater A The girt D is preferably narrowed or beveled on its upper edge as shown to form a fulcrum for the pedals. The girt is also slotted as at d to provide a bearing surface or fulcrum for the rear end of the shipping lever J.

The pedals E are constructed as short plates, and extend across the machine, and are of convenient number and width. Each plate rests upon the upper edge of the girt D and is provided with means such as the notch e to hold it in place on the girt so that preferably one end will be longer than the other, the longer end extending under th ticing roll C. The other end of each plate has a flange e which extends dowrr wardly from it and is perforated as at 6 From each perforation hangs a link 6 which is preferably open as shown in Fig. 2 so as to be easily removed from the pedal if desired.

F, F are yokes which connect links 6 e G, G are yokes which connect links f, f one of which is suspended from each yoke F. H is a still longer yoke which is suspended from links 9 which hang from the yokes G. The number of links and yokes will of course depend in any case upon the number of plates used. This construction does away with the rearwardly-extending long arms usual in this type of machine and makes a compact mechanism which simplifies construction materially.

J is a lever one'end of which rests against the under side of the girt D. The other end of the lever J is hook-shaped to receive the eye is in the upper end of the connecting rod K. Intermediate theends of the lever J it is notched as at j to rest upon the yoke H. The lower end of the connecting rod K is connected to an arm Z on a shaft L at the other end of which is a slotted upright arm Z the whole forming a bell-crank mechanism. The arm Z is connected by a second connecting rod m with an arm m on a shaft m mounted in the frame A. The shaft m also carries a segment gear M which engages a rack M mounted to slide longitudinally and carrying a belt shifter inclicated at M by which the belt N is moved along the cone pulleys N to change the speed of the rolls as occasion may require. It will be noted that in this construction the girt serves as a support for the plates and that the strain upon it is counterbalanced because it also serves as a fulcrum for the lever J which presses on its under side. As a result this support may be made quite light.

The operation of this mechanism and its possibilities will be easily understood. As the lap is drawn along by the feed rolls it passes over the plates and under the ticing roll at a normal speed. When any bunch or undue thickening of the lap reaches the ticing roll it tends to depress the free long end of the plate, thus raising the long arm of the lever J and by means of the connections between itand the segment gear M, moving the segment gear and by means of the rack M shifting the position of the belt N on the cone pulleys N and thus slowing down the speed of the feed rolls B, B so that they can takecare of the lap and destrain upon the girt, at the same time proalever one end of which is fulcrumed on the problem.

liver it in a uniform condition.

Our invention; is a simple solution of a It takes but little room on the machine; in fact, it is very economical of space compared with other mechanisms used for the purpose, and has proved very practic'able; In details of construction it may of course be altered without departing from its essentials, an important feature of it beingthe mounting of the plates on the girt as a fulcrum andthe use of theunder side of the same girt as a fulcrum for the lever so thatthesepressures support each other and to a considerable'extent neutralize the viding a firm bearing for each part. The

platesare short and they are connected by simple connections with the lever so as to get'most efficient results with a few numbelt shifter therefor, and means comprising ;a lever one end of wh1ch 1s connected to said beltshi-fter, the other end engaging said girt' and-intermediate connections connecting saidlever with said plates whereby said plates may cause-the operation ofsaid belt shifter.

2. In a machine of the kind described, a feed mechanism and an evener mechanism comprising a gllt, a series-of plates 1nounted thereon, a ticing roll mounted above said :plates, a belt shifter and connections between said belt shifter and said plates comprising under side of said girt, means for-connecting the other endof said lever with said belt ends of said lever connecting said lever and sald plates, whereby the movement of said shifter and connections intermediate the two plates will cause the operation of the belt shifter and the changing of the speed of the feed.

3. In amachine of the kind described, a' feed mechanism and an evener mechanism comprising a ticing roll, plates located thereand the belt shifter operated.

4. In an evener mechanism, a pedal having an integral flange upon its rear end, its other-end being adapted to lie under a ticing'roll, said pedal having on its under side means to hold it in place upon a support.

5. In a machine of the kind described, an

evener mechanismcomprising a girt, a plurality of shortplates fulcrumed -upon the girt, a ticing roll cooperating with the plates upon one side of their fulcrums, a reducing motion connected directly with the plates upon the other side'of their fulcrums, and a belt shifter mecha'nism operated bythe reducing motion.

6. In a machine of the kind described, agirt, a ticing-roll, a plurality of plates fulcrumed upon the girt, each plate cooperating with the ticing roll upon oneside of its fulcrum and having an integral perforated flange upon the other side of its fulcrunua' belt shifter mechanism, and connections be' tween the perforated fiangesand; the belt shifter mechanism. a
